1.6L Miata Weight | 2255 lbs?

Yep, it's still 2255 for a 90-93 ITA Miata. A 90-93 SM racing in ITA is 2300?

I needed to get those decals too. Could someone please tell me the weight for a 95 Miata in ITA trim, running in ITA. I read the GCR and it seems to imply 2380.

I was thinking of running STL as an additional "practice" class, and the weight seems to be 2340 for a 1.8. Is that correct ?

The GCR also says, "GCR listed IT cars of 2 liters
and less engine displacement, 1985 and newer, may compete in
STL under their current IT specifications."

So is that 2380 or 2340 for STL ?

Thanks

Whatever your ITA weight is, assuming you meet all ITA specs.

1.8L STL cars are going to 2430# as a base weight effective March 30th (with RWD having to add another 2.5%), so there's no value in your running in STL trim, unless you want to pull your restrictor plate. But note that if you do that, you must meet ALL STL specs, including weight and ride height (for example), and all mandatory safety equipment (e.g., dash bar).

Stick with ITA prep.

Greg, what is the total RWD adder now in STL? 5 or 7.5%?

If you're running your 1.6 Miata in ITA, remember a torsen and de-powered Power steering rack are not legal.

Among other things like the 94-97 chassis bracing, ride heights usually, etc. But nobody has protested to date IIRC because the performance isn't up to IT spec...but there are no connections between IT and SM so it could flip flop.
